Vista has an inbuilt undelete system based on Windows Server 2003's versioning file system, Microsoft has revealed. The technology, which is automatically switched on in Vista, will be a boon for anyone who has accidentally overwritten their PhD thesis with a BPAY receipt.

... but I sure as hell hope that there is a secure delete along with this tool, because there are times when you want something truely deleted, and not have someone coming up behind you to find your private infomation (banking, etc) - I think this feature lends itself more to law enforcement than it does home users?
